Issues for ECDCs Pan European approach to VBD s VBDs belong to different contexts in different countries Priorities for surveilance/interventions depend on the context of VBD To determine the context of a VBD, data is needed from each country The quality of data depends on the quality/ level of the VBD surveillance feedback system of country Qualtity/Level of VBD surveillance feedback system depends on perceived urgency of local governments VBORNET aims to assist ECDC and member states in their assessments of VBD
